Description

Method for producing polyalphaolefins using ionic liquid catalyzed olefin oligomerization
Technical Field
The present invention relates to a process for making an oligomer product and/or a polyalphaolefin. More particularly, the present invention relates to a process for producing oligomeric products and/or polyalphaolefins using ionic liquid catalyzed oligomerization of olefins (e.g., normal alpha olefins, linear internal olefins, etc.).
Background
Oligomer products, hydrogenated oligomer products (e.g., polyalphaolefins), and derivatives thereof are used to produce a wide variety of articles (e.g., synthetic lubricants or lubricant additives). The use of a particular oligomer product and/or hydrogenated oligomer product in a particular application will depend on the type of physical and/or mechanical properties exhibited by the oligomer product and/or hydrogenated oligomer product, and such properties may be the result of the process used to produce the particular oligomer product and or hydrogenated oligomer product, e.g., the reaction conditions under which the oligomer product can be produced. Therefore, there is also a need to develop and improve processes for producing these oligomers and hydrogenated oligomer products.
Disclosure of Invention
Embodiments of a process are disclosed that generally include contacting i) a monomer or mixture of monomers, ii) a halogenated aluminate ionic liquid, and iii) one or more halide components (e.g., bronsted acids, organic halides) in a reaction zone, and oligomerizing the monomer or mixture of monomers in the reaction zone to form an oligomer product. The oligomer product having the properties described herein can be separated into one or more fractions, and the one or more fractions can be hydrogenated to produce polyalphaolefins. Separating one or more fractions from the oligomer product may include various techniques and separations as disclosed herein.
Embodiments of catalyst systems comprising a haloaluminate ionic liquid and a halide component are also disclosed. The catalyst system can have various features as described herein that facilitate production of the disclosed oligomer products.

Detailed Description
Disclosed herein are methods of making oligomer products and/or hydrogenated oligomer products (e.g., polyalphaolefins). In one embodiment, the process of the present invention comprises oligomerizing monomers in the presence of an ionic liquid (e.g., a haloaluminate ionic liquid), an organic halide component, or both, to produce an oligomer product. At least a portion of the oligomer product may be recovered and/or hydrogenated to produce what is commonly referred to as Polyalphaolefin (PAO). In one embodiment, such a process may produce a PAO having desired properties (e.g., viscosity, pour point, and/or viscosity index) among other properties.
In order to more clearly define the terms used herein, the following definitions are provided. The following definitions apply to the present invention unless otherwise indicated. If a term is used herein, but is not explicitly defined herein, then the definition in the general catalogues of the International Union of theory and applied chemistry (IUPAC Complex of Chemical technology), 2 nd edition (1997) may be used provided that the definition does not conflict with any other disclosure or definition used herein or render uncertain or infeasible any claim to which the definition applies. In the event that any definition or use provided by any document incorporated by reference conflicts with the definition or use provided herein, the definition or use provided herein prevails.
The groups of the elements of the periodic table are represented using the numbering scheme indicated in the periodic table of the elements of the version published in chemical and engineering news, 63(5),27, 1985. In some cases, the family of elements may be represented using the common name assigned to the family; for example, the group 1 element is an alkaline earth metal (or alkali metal), the group 2 element is an alkaline earth metal (or alkali metal), the group 3-12 elements are transition metals, and the group 17 element is a halogen.
A chemical "group" is described in terms of how the group is formally derived from a reference or "parent" compound, for example by the number of hydrogen atoms formally removed from the parent compound (thereby yielding the group), even if the group is not actually synthesized in this manner. These groups may be used as substituents or may be coordinated or bonded to the metal atom. For example, "alkyl" is formally derived by the removal of one hydrogen atom from an alkane, while "alkylene" is formally derived by the removal of two hydrogen atoms from an alkane. In addition, more general terms may be used to encompass various groups that are formally derived by removing any number of ("one or more") hydrogen atoms from a parent compound (which in this example may be described as an "alkane," and which includes "alkyl", "alkylene", and substances that remove three or more hydrogen atoms (if the case requires) from an alkane). Throughout the present invention, a substituent, ligand, or other chemical moiety may constitute a particular "group" meaning that the group, when employed as described, will follow well-known chemical structures and bonding rules. When describing a group as "obtained," "from," "formed," or "formed from," such terms are used in a formal sense and are not intended to represent any particular synthetic method or procedure unless otherwise specified or the context requires otherwise.
When used to describe a compound or group, for example when referring to a substituted analog of a particular compound or group, the term "substituted" is intended to describe any non-hydrogen moiety that formally replaces a hydrogen in that group and is not limiting. A group or groups may also be referred to herein as "unsubstituted" or an equivalent term such as "unsubstituted," which refers to the original group in which the non-hydrogen moiety did not replace a hydrogen in the group. "substituted" is intended to be non-limiting and includes inorganic substituents or organic substituents.
Unless otherwise specified, any carbon-containing group for which the number of carbon atoms is not specified can have 1,2, 3,4, 5,6, 7,8, 9, 10, 11, 12, 13, 14, 15, 16,17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 carbon atoms, or any range or combination of ranges between these values, according to appropriate chemical convention. For example, unless otherwise specified, any carbon-containing group can have 1 to 30 carbon atoms, 1 to 25 carbon atoms, 1 to 20 carbon atoms, 1 to 15 carbon atoms, 1 to 10 carbon atoms, or 1 to 5 carbon atoms, and the like. In addition, other identifier or defining terms may be used to indicate the presence or absence of particular substituents, particular regiochemistry and/or stereochemistry, or the presence or absence of branched base structures or backbones.
In the present invention, the general rules of organic nomenclature prevail. For example, when referring to a substituted compound or group, reference to the substitution pattern is used to indicate that the indicated group is at the indicated position, and all other unspecified positions are hydrogen. For example, reference to a 4-substituted phenyl group means that the non-hydrogen substituent is located at the 4-position and the hydrogen is located at the 2-, 3-, 5-, and 6-positions. By way of further example, reference to a 3-substituted naphthalen-2-yl group indicates that the non-hydrogen substituent is in the 3-position and that hydrogen is in the 1-, 4-, 5-, 6-, 7-, and 8-positions. References to a compound or group having a substitution at a position other than the indicated position will be described using inclusion or some other alternative language. For example, reference to a phenyl group containing a substituent at the 4 position refers to a group having a non-hydrogen atom at the 4 position and having hydrogen or any non-hydrogen group at the 2,3, 5 and 6 positions.
With respect to transitional terms or phrases of the claims, the transitional term "comprising" synonymous with "including", "containing", "having" or "characterized by" is inclusive or open-ended and does not exclude additional unrecited elements or method steps. The transitional phrase "consisting of … …" does not include any elements, steps, or components not recited in the claims. The transitional phrase "consisting essentially of … …" limits the scope of the claims to the named substances or steps, as well as those substances or steps that do not materially affect the basic and novel characteristics of the claimed invention. The term "consisting essentially of … …" embraces the scope between closed claims like "consisting of … …" and fully open claims like "comprising". In the absence of a contrary indication, when describing a compound or composition, "consisting essentially of … …" should not be construed as "comprising," but rather is intended to describe that the recited component includes material that does not materially alter the composition or method to which the term applies. For example, a feedstock consisting essentially of substance a can include impurities typically present in a sample of a stated compound or composition that is commercially produced or commercially available. When the claims include different features and/or types of features (e.g., method steps, material features, and/or product features, among other possibilities), the transitional terms "comprising," "consisting essentially of … …," and "consisting of … …" apply only to the type of features used and may have different transitional terms or phrases used for different features within the claims. For example, a process can comprise several recited steps (and other non-recited steps), but be prepared using a catalyst system consisting of, or alternatively consisting essentially of, the particular steps, but utilizing a catalyst system comprising the recited components and other non-recited components.
Although the compositions and methods are described in terms of "comprising" (or other broad term) various components and/or steps, the compositions and methods can also be described using narrower terms such as "consisting essentially of" or "consisting of" the various components and/or steps.
Use of the term "optionally" with respect to any element of a claim is intended to mean that the subject element is required, or alternatively, is not required. Both alternatives are intended to fall within the scope of the claims.
The terms "a", "an" and "the" are intended to include a plurality of alternatives, such as at least one, unless expressly specified otherwise. For any particular compound or group disclosed herein, unless otherwise specified, any name or structure given is intended to include all conformational isomers, positional isomers, and stereoisomers that may arise from a particular set of substituents. For example, general mention of pentane includes n-pentane, 2-methyl-butane and 2, 2-dimethylpropane, and general mention of butyl includes n-butyl, sec-butyl, isobutyl and tert-butyl (t-butyl) or tert-butyl (tert-butyl). Unless otherwise specified, the name or structure also includes all enantiomers, diastereomers, and other optical isomers (whether in enantiomeric or racemic forms), as well as mixtures of stereoisomers, as recognized by the skilled artisan.
Whenever used in the present specification and claims, the term "olefin" refers to a hydrocarbon having at least one carbon-carbon double bond that is not an aromatic ring or part of an aromatic ring system. Unless specifically indicated otherwise, the term "olefin" includes aliphatic and aromatic, cyclic and acyclic, and/or straight or branched chain hydrocarbons having at least one carbon-carbon double bond that is not part of an aromatic ring or ring system. Olefins having only one, only two, only three, etc. carbon-carbon double bonds of … … can be identified by using the terms "mono", "di", "tri", etc. … … within the name of the olefin. The olefin may be further identified by the position of the carbon-carbon double bond.
Whenever used in the present specification and claims, the term "olefin" refers to a straight or branched chain aliphatic hydrocarbon olefin having one or more carbon-carbon double bonds. Olefins having multiple bonds of only one, only two, only three, etc. … … can be identified by using the terms "mono", "di", "tri", etc. … … within the name. For example, alkamonoolefins, alkadienes, and alkatrienes refer to straight or branched chain acyclic hydrocarbon olefins having only one carbon-carbon double bond (acyclic, having the general formula CnH2n), only two carbon-carbon double bonds (acyclic, having the general formula CnH2n-2), and only three carbon-carbon double bonds (acyclic, having the general formula CnH2n-4), respectively. The olefin may be further identified by the position of the carbon-carbon double bond. Other identifiers may be used to indicate the presence or absence of a particular group within an olefin. For example, a halogenated olefin refers to an olefin in which one or more hydrogen atoms are replaced with halogen atoms.
The term "alpha olefin" as used in the specification and claims refers to an olefin having a carbon-carbon double bond between the first and second carbon atoms of the longest continuous chain of carbon atoms. Unless specifically indicated otherwise, the term "alpha olefin" includes both straight chain and branched alpha olefins. In the case of branched alpha olefins, the branching may be at the 2-position (vinylidene) and/or the 3-position or higher relative to the olefinic double bond. Whenever used in the present specification and claims, the term "vinylidene" refers to an alpha olefin having a branch at the 2-position relative to the olefinic double bond. Unless specifically indicated, the term "alpha olefin" by itself does not indicate the presence or absence of other carbon-carbon double bonds.
The term "linear alpha olefin" as used herein refers to a linear olefin having a carbon-carbon double bond between the first and second carbon atoms. Unless specifically indicated, the term "linear alpha olefin" by itself does not indicate the presence or absence of other carbon-carbon double bonds.
Whenever used in this specification and claims, the term "normal alpha olefin" refers to a straight chain aliphatic mono-olefin having a carbon-carbon double bond between the first and second carbon atoms. It should be noted that "normal alpha olefin" is not synonymous with "linear alpha olefin" because the term "linear alpha olefin" may include linear olefinic compounds having a double bond between the first and second carbon atoms and an additional double bond.
Whenever used in the present specification and claims, the term "consisting essentially of n-alpha olefins" or variants thereof refers to commercially available n-alpha olefin products. Commercially available normal alpha olefin products may contain non-normal alpha olefin impurities such as vinylidene groups, internal olefins, branched alpha olefins, paraffins, and diolefins, among other impurities, that are not removed during the normal alpha olefin production process. One will readily recognize that the identity and quantity of a particular impurity present in a commercial normal alpha olefin product will depend on the source of the commercial normal alpha olefin product. Thus, unless specifically indicated, the term "consisting essentially of normal alpha olefins" and variations thereof is not intended to limit the amount/quantity of the nonlinear alpha olefin component more severely than the amount/quantity present in a particular commercial normal alpha olefin product.
The term "1, 2-disubstituted alkene" as used herein refers to a compound having at least one carbon-carbon double bond and one and only one substituent on each carbon atom of the carbon-carbon double bond. The term "tri-substituted alkene" as used herein refers to a compound having at least one carbon-carbon double bond, wherein two substituents are attached to one carbon of the alkene carbon-carbon double bond and one and only one substituent is attached to the other carbon atom of the alkene carbon-carbon double bond.
As used in this specification, the phrases "in the substantial absence of an organic reaction medium", "in the absence of an organic diluent", "in the substantial absence of an organic diluent", "in the absence of an organic solvent", "in the substantial absence of an organic solvent" and the like refer to a step (e.g., a step of forming an oligomer product) under conditions in which the concentration of reactants (e.g., monomer concentration) is not significantly reduced by non-reactive components. It will be apparent to those skilled in the art, and with the aid of the present invention, the terms "organic medium", "organic diluent" and "organic solvent" refer to a specific compound which is introduced to reduce the concentration of a reactant (e.g. monomer) or to play a particular role in the process (such as adjusting the heat of reaction or providing fluidity to the reaction mixture), and which does not play a role as a reactant in the oligomerization reaction. Thus, the phrases "in the substantial absence of an organic reaction medium", "in the absence of an organic diluent", "in the substantial absence of an organic diluent", "in the absence of an organic solvent", "in the substantial absence of an organic solvent" and similar phrases are not intended to limit the invention to the complete absence of impurity compounds within a monomer or feed stream that may otherwise, or in greater amounts, be understood to function as a diluent or solvent. For example, although decane may in some instances be an "organic diluent" or an "organic solvent" or an "organic reaction medium", the presence of a small or minor amount (e.g., about ≦ 1.5%) of decane as an impurity in the 1-decene monomer stream does not significantly reduce the concentration of 1-decene or play a particular role in the reaction system and is therefore not precluded by the use of the phrases "in the substantial absence of an organic reaction medium", "in the absence of an organic diluent", "in the substantial absence of an organic diluent", "in the absence of an organic solvent", "in the substantial absence of an organic solvent" or similar phrases. If desired, the phrases "in the substantial absence of an organic reaction medium", "in the absence of an organic diluent", "in the substantial absence of an organic diluent", "in the absence of an organic solvent", "in the substantial absence of an organic solvent" and the like can be defined to mean 5 wt.% or less, 4 wt.% or less, 3 wt.% or less, 2.5 wt.% or less, 2 wt.% or less, 1.5 wt.% or less, 1 wt.% or less, 0.8 wt.% or less, 0.6 wt.% or less, or 0.5 wt.% of an organic reaction medium, organic diluent or organic solvent.
The term "room temperature" or "ambient temperature" is used herein to describe any temperature from 15 ℃ to 35 ℃, wherein no external heat or cooling source is applied directly to the reaction vessel. Thus, the terms "room temperature" and "ambient temperature" include individual temperatures ranging from 15 ℃ to 35 ℃ as well as any and all ranges, subranges, and combinations of subranges wherein no external heat or cooling source is applied directly to the reaction vessel. The term "atmospheric pressure" is used herein to describe the earth's atmospheric pressure, wherein no external pressure regulating device is used. Typically, unless operating at extreme Earth altitudes, "atmospheric pressure" is about 1 atmosphere (alternatively, about 14.7psi or about 101 kPa).
The features provided as a minimum in the present disclosure may be alternatively described as "at least" or "greater than or equal to" any minimum stated for the features disclosed herein. The features provided as maxima in the present invention may optionally be described as "less than or equal to" any maximum recited for the features disclosed herein.

It should be noted, however, that the processes and/or methods described herein can have multiple steps, features (e.g., ratios of reagents, formation conditions, among other considerations), and/or multiple compounds with the same general descriptors.

Generally, the pressure that can be used as conditions capable of forming the oligomer product (e.g., the pressure of reaction zone 10) can be any pressure that can assist in forming the oligomer product. In one embodiment, the minimum pressure that can be used as conditions capable of forming an oligomer product can be 0psig (0kPa) or 0.1psig (0.69 kPa).

Ionic liquids are a class of compounds that consist entirely of ions and are normally liquid at or below process temperatures. Salts composed entirely of ions are often solids with high melting points (e.g., above 450 ℃). These solids are often referred to as 'molten salts' when heated above their melting points. For example, sodium chloride is a common 'molten salt' with a melting point of 800 ℃. Ionic liquids differ from 'molten salts' in that they have low melting points, for example-100 ℃ to 200 ℃. Ionic liquids tend to be liquids over a wide temperature range, with some ionic liquids having a liquid range as high as 300 ℃ or higher. Ionic liquids are generally non-volatile, having no effective vapor pressure. Many ionic liquids are stable to air and water and can be good solvents for a wide range of inorganic, organic, and polymeric substances.
The properties of ionic liquids can be adjusted by varying the cation and cation pairing. Ionic liquids and some commercial applications thereof, such as journal of chemical and biological technology (j.chem.tech. biotechnol), 1997, vol.68 (4), p.351-356; journal of physically condensed Matter (J. Phys. condensed Matter), 5 (journal of 34B), B99-B106 (1993); news of chemistry and Engineering (Chemical and Engineering News), 30.3.1998, pages 32-37; journal of materials chemistry (j. mater.chem.), 1998, volume 8, page 2627-2636; and chemical review (chem.rev.) 1999, volume 99, pages 2071-2084.
Many ionic liquids are amine-based. Among the most common ionic liquids are those formed by the following process: the ionic liquids are formed by reacting a nitrogen-containing heterocycle (cyclic amine), preferably a nitrogen-containing aromatic ring (aromatic amine), with an alkylating agent (e.g., an alkyl halide) to form a quaternary ammonium salt, followed by ion exchange or other suitable reaction to introduce the appropriate counter anion species. Examples of suitable heteroaromatic rings include pyridine and its derivatives, imidazole and its derivatives, and pyrrole and its derivatives. These rings may be alkylated with different alkylating agents to incorporate a wide range of alkyl groups on the nitrogen, including straight, branched or cyclic C1-20An alkyl group. Due to being larger than C12The alkyl groups of (A) can produce undesirable solid products with some amines, C is often used1-12An alkyl group. Ionic liquids based on pyridinium and imidazolium salts are probably the most commonly used ionic liquids. Other amine-based ionic liquids including cyclic and acyclic quaternary ammonium salts are often used. Phosphonium and sulfonium based ionic liquids have also been used.
Counter ions that have been used in ionic liquids include chloroaluminate, bromoaluminate, gallium chloride, tetrafluoroborate, tetrachlorate, hexafluorophosphate, nitrate, trifluoromethanesulfonate, methanesulfonate, p-toluenesulfonate, hexafluoroantimonate, hexafluoroarsenate, tetrachloroaluminate, tetrabromoaluminate, perchlorate, hydroxide anion, copper dichloride anion, iron trichloride anion, antimony hexafluoride, copper dichloride anion, zinc trichloride anion, and various lanthanum, potassium, lithium, nickel, cobalt, manganese, and other metal ions.

In various embodiments, the oligomer product can be formed in the presence of (e.g., reaction zone 10 comprises) an organic reaction medium. The organic reaction medium may be C3To C18A saturated hydrocarbon. The organic reaction medium may be introduced into reaction zone 10 prior to, simultaneously with, or subsequent to the introduction of i) the monomer, ii) the halide component, iii) the haloaluminate ionic liquid, or iv) combinations thereof into reaction zone 10. In one embodiment, the organic reaction medium may be combined with any of the monomers, halide components, halogenated aluminate ionic liquids, or combinations thereof prior to introduction of the organic reaction medium into reaction zone 10. In various embodiments, the organic reaction medium can be introduced into reaction zone 10 periodically or continuously.

In various embodiments, the oligomer product can be formed in an inert atmosphere (e.g., contained in reaction zone 10). The inert atmosphere may include the presence or absence of an organic reaction medium.
Returning to fig. 1, the reaction zone effluent is withdrawn from reaction zone 10 via stream 12. The discharge of the reaction zone effluent may occur periodically or continuously. Separator 20 can separate the reaction zone effluent received from stream 12 into a first stream 22 and a second stream 24. First stream 22 may comprise all or a portion of the halogenated aluminate ionic liquid (optionally, all or a portion of any halide component and/or organic reaction medium, if used) received into separator 20 from stream 12 (e.g., all or a portion of the halogenated aluminate ionic liquid in the reaction zone effluent). The second stream 24 can comprise, consist essentially of, or consist of unreacted monomers, oligomer products, and optionally residual haloaluminate ionic liquid and/or organic reaction medium (if used). In various embodiments, the separator 20 may be a coalescer, a centrifuge, a membrane, or any combination thereof. The operating configuration and conditions of the separator 20 may be conditions known to those skilled in the art with the aid of the present invention.
The halogenated aluminate ionic liquid (and optionally any halide component) in the first stream 22 can be recycled to the reaction zone 10. In one embodiment, the halogenated aluminate liquid in the first stream 22 flows to a regenerator 30 where the halogenated aluminate ionic liquid may be regenerated before being reintroduced into the reaction zone 10. The halogenated aluminate ionic liquid may be regenerated by contacting the halogenated aluminate ionic liquid with aluminum under regeneration conditions.
Should be notedTo that, the regenerator 30 may be constructed of one or more pieces of equipment; such as reactors and separators, among other options. Typically, the halogenated aluminate ionic liquid may be regenerated by contact with aluminum metal. In some embodiments, the halogenated aluminate ionic liquid is contacted with aluminum metal in the presence of hydrogen. The aluminum may be in the form of fine particles, granules, sponge, gauze, or the like; alternatively, the aluminum may be in macroscopic form that may include wires, foils, fine particles, sponges, gauze, granules, and the like; or alternatively, the aluminum may be in microscopic form which may include powder, fume, colloidal suspension, and compressed metal film. Typically, when hydrogen is used, the halogenated aluminate ionic liquid may be contacted with the aluminum at a hydrogen partial pressure in the range of 50psig (345kPa) to 2500psig (17.2 MPa); or alternatively from 100psig (689kPa) to 2,500psig (17.2 MPa). The regeneration conditions for the ionic liquid may include a temperature of from-20 ℃ to 200 ℃ (or alternatively from 50 ℃ to 100 ℃) and a contact time in the range of from 0.1 minutes to 24 hours (or alternatively from 30 minutes to 2 hours). In some embodiments, the ionic liquid may be regenerated in an inert hydrocarbon solvent (e.g., C)5To C15A hydrocarbon, optionally C5To C18A hydrocarbon, optionally C5To C15N-hydrocarbon, optionally C5To C18Normal hydrocarbons). Further information on the regeneration of haloaluminate ionic liquids can be found in US7,732,364B2, US7807,597B2, US7,732,363B2 and US7,691,771B2.
In fig. 1, the regenerated haloaluminate ionic liquid exits regenerator 30 via stream 32. Fresh haloaluminate ionic liquid in stream 6 is combined with recycled haloaluminate ionic liquid in stream 32. The amount of haloaluminate ionic liquid flowing in feed stream 8 may be equal to the amount of fresh haloaluminate ionic liquid flowing in stream 6 plus the amount of recycled haloaluminate ionic liquid flowing in stream 32. In various embodiments, the weight ratio of fresh haloaluminate ionic liquid to recycled haloaluminate ionic liquid (e.g., in feed stream 8, in reaction zone 10, or both) may be from 0.1:1 to 10: 1. In some embodiments, the recycled halogenated aluminate ionic liquid may not be regenerated. In embodiments where the halogenated aluminate ionic liquid is not regenerated, the weight ratio of fresh halogenated aluminate ionic liquid to recycled halogenated aluminate ionic liquid may be the same as the weight ratio of fresh halogenated aluminate ionic liquid to recycled halogenated aluminate ionic liquid when the ionic liquid is regenerated. In other embodiments, the recycled haloaluminate ionic liquid (regenerated or not) may be introduced directly into the reaction zone 10; or alternatively, the recycled haloaluminate ionic liquid (regenerated or not) may be introduced into any feed stream containing the haloaluminate ionic liquid disclosed herein that will be directed to reaction zone 10.
In various embodiments, the second stream 24 may optionally be treated to remove any residual catalyst system components (e.g., halogenated aluminate ionic liquid, chloride components, or both) present in the second stream 24. In embodiments where the second stream 24 is treated to remove residual catalyst system components, the second stream 24 can be flowed to a treatment unit (not shown) to quench or remove residual catalyst system components in order to separate substantially all of the halogenated aluminate ionic liquid and/or halide components from unreacted monomer and oligomer products. Removal of "substantially all" of the halogenated aluminate ionic liquid may involve removing the halogenated aluminate ionic liquid from stream 24 to form a stream comprising less than 5,4, 3,2, 1, 0.5, 0.4, 0.3, 0.2, or 0.1 mol% of the halogenated aluminate ionic liquid in the reaction zone effluent (stream 12). Similarly, the removal of "substantially all" of the halide component can involve removing the halide component from stream 24 to form a stream comprising less than 5,4, 3,2, 1, 0.5, 0.4, 0.3, 0.2, or 0.1 mol% of the halide component in the reaction zone effluent (stream 12). In embodiments having a treatment unit, a detergent (e.g., aqueous alkali metal hydroxide or anhydrous ammonia) may be contacted with second stream 24 in the treatment unit. The detergent may help remove residual catalyst system components (e.g., haloaluminate ionic liquid and/or halide components) from the unreacted monomer and oligomer products. Once treated in the treatment unit, treated second stream 24 comprising unreacted monomer and oligomer product (and any organic reaction medium, if used) and the detergent contacted with second stream 24 may be passed from the treatment unit via separate streams and further treated as described herein.
The embodiment of the oligomerization reaction shown in fig. 1 may include controlling certain parameters to obtain a selected average molecular weight (Mn) of the oligomer product. For example, the average molecular weight (Mn) of the oligomer product can be controlled by: selecting an average molecular weight for the oligomer product, and adjusting (i) a molar ratio of carbon-carbon double bonds of the monomer to aluminum in the haloaluminate ionic liquid, (ii) a molar ratio of halide in the halide component to aluminum in the haloaluminate ionic liquid, or a combination of (i) and (ii) to obtain the selected average molecular weight of the oligomer product. Alternatively or additionally, the average molecular weight (Mn) of the oligomer product can be controlled by: selecting an average molecular weight for the oligomer product, and adjusting (i) a temperature at which the oligomer product is formed, (ii) a time at which the oligomer product can be formed, or iii) any combination of (i) and (ii).
Embodiments of the invention include producing one or more hydrogenated fractions comprising all or a portion of the hydrogenated oligomer product. In embodiments of the invention, the production of one or more hydrogenated fractions comprising all or part of the hydrogenated oligomer product may comprise separating one or more fractions of all or part of the oligomer product, followed by hydrogenation of at least one of the one or more fractions. In other embodiments, the stream comprising all or a portion of the oligomer product may be hydrogenated to produce a fraction comprising all or a portion of the hydrogenated oligomer product, and then the fraction comprising all or a portion of the hydrogenated oligomer product may be separated into one or more hydrogenated fractions comprising all or a portion of the hydrogenated oligomer product. In other embodiments, a stream consisting essentially of all or part of the oligomer product may be hydrogenated to produce a fraction comprising all or part of the hydrogenated oligomer product, and then the fraction comprising all or part of the hydrogenated oligomer product may be separated into one or more all or part hydrogenated fractions containing the hydrogenated oligomer product. Typically, the production of one or more hydrogenated fractions comprising all or part of the hydrogenated oligomer product may comprise a combination of a separation step and a hydrogenation step.
In one embodiment, the process described herein may include separating one or more fractions of all or a portion of the oligomer product. Separating one or more fractions of all or a portion of the oligomer product may include: I) separating the oligomer product from unreacted monomer, fractionating the oligomer product into one or more fractions, and optionally recycling the unreacted monomer to reaction zone 10; separating the oligomer product from the monomer and organic reaction medium (if used), fractionating the oligomer product into one or more fractions, and optionally recycling unreacted monomer and organic reaction medium to reaction zone 10; separating the heavier portion of the oligomer products from the lighter portion of the unreacted monomer and oligomer products, fractionating the heavier portion into one or more fractions, and optionally recycling the lighter portion of the unreacted monomer and oligomer products to reaction zone 10; or separating the heavier portion of the oligomer product from the monomer, the lighter portion of the oligomer product, and the organic reaction medium, fractionating the heavier portion of the oligomer product, and optionally recycling unreacted monomer, the lighter portion of the oligomer product, and/or the organic reaction medium to reaction zone 10. The separation and fractionation may be carried out using any known process. In some embodiments, one or more of the separating and fractionating steps may be performed by distillation.
Figures 2 through 4 show various embodiments of separating one or more fractions of all or a portion of the oligomer product and hydrogenating at least one of the one or more fractions of all or a portion of the oligomer product.
Referring to fig. 2, separator 40 receives second stream 24 (which may optionally be treated to remove residual catalyst system components). In separator 40, unreacted monomer, organic reaction medium (if used), and oligomer product can be separated into a third stream 42 and a fourth stream 44. The composition of the third stream 42 and the fourth stream 44 includes several embodiments. A first embodiment of the third stream 42 and the fourth stream 44 comprises: a third stream 42 comprising unreacted monomerOrganic reaction medium (if used) and ≦ C18An oligomer, or consisting essentially of, or consisting of; a fourth stream 44 comprising ≧ C19An oligomer, or consisting essentially of, or consisting of, an oligomer. A second embodiment of the third stream 42 and the fourth stream 44 comprises: a third stream comprising unreacted monomers, organic reaction medium (if used) and ≦ C25An oligomer, or consisting essentially of, or consisting of; a fourth stream 44 comprising ≧ C26An oligomer, or consisting essentially of, or consisting of, an oligomer. A third embodiment of the third stream 42 and the fourth stream 44 comprises: a third stream 42 comprising, consisting essentially of, or consisting of unreacted monomer, organic reaction medium (if used); a fourth stream 44 comprising, consisting essentially of, or consisting of the oligomer product. A fourth embodiment of the third stream 42 and the fourth stream 44 comprises: a third stream 42 comprising, consisting essentially of, or consisting of unreacted monomer, organic reaction medium (if used), and dimer; a fourth stream 44 comprising, consisting essentially of, or consisting of trimers and heavier oligomers (also referred to herein as "trimers + oligomers"). ". ltoreq.C for each example of the third stream 4218Low polymer and C is less than or equal to25Oligomers "and" dimers "may be referred to as" lighter oligomers ". "≧ C for embodiments of the fourth stream 4419Oligomer, "≧ C26Oligomers "and" trimers + oligomers "may be referred to as" heavier oligomers ". Various embodiments contemplate that the organic reaction medium (if used) may be included in stream 24 and may be separated from the monomer and oligomer products prior to entering separator 40, or may be separated from any all or a portion of the oligomer products described herein by separator 40 into third stream 42.
Figure 2 shows that components in third stream 42, such as unreacted monomers, lighter oligomers, organic reaction medium (if used), or any combination thereof, can optionally be recycled to reaction zone 10. In embodiments where the components of the third stream are recycled to the reactor, the components of the third stream 42 can optionally be contacted with molecular sieves, alumina, silica gel, activated carbon, or any combination thereof (not shown) before being recycled to the reaction zone 10. In embodiments where the third stream 42 may optionally be contacted with molecular sieves, alumina, silica gel, activated carbon, or any combination thereof, the components of the third stream 42 may flow from the separator 40 to a contacting unit (not shown) where the components are contacted with molecular sieves, alumina, silica gel, activated carbon, or any combination thereof. Contacted components (e.g., unreacted monomers, lighter oligomers, organic reaction medium (if used), or any combination thereof) can exit the contacting unit and can be recycled to reaction zone 10 of fig. 1. In one embodiment, separator 40 is a distillation column. It should be noted that although fig. 2 shows the third stream 42 being recycled to the reactor in its entirety, it is contemplated that only a portion of the third stream 42 may be recycled to the reaction, may undergo further separation to provide a stream comprising unreacted monomers, lighter oligomers (if present in the third stream 42), and/or all or a portion of the components may be stored for a period of time before being recycled to the reaction zone 10 of fig. 1.
In fig. 2, the fourth stream 44 flows to the fractionation zone 50. In fractionation zone 50, the components of fourth stream 44 (e.g., all or a portion of the oligomer product, such as heavier oligomers of the oligomer product) can be fractionated into one or more fractions using one or more separation devices (e.g., distillation columns). In embodiments where the fourth stream 44 comprises oligomer product, the fractionation zone 50 can fractionate the oligomer product into one or more fractions comprising all or a portion of the oligomer product.

In embodiments where the fourth stream 44 comprises trimer + oligomers of oligomer products, the one or more fractions comprising all or a portion of the trimer + oligomers may be selected from the group consisting of: a) a fraction comprising 80 to 90% by weight of trimers and 8 to 18% by weight of tetramers, b) a fraction comprising 85 to 95% by weight of trimers and 3 to 13% by weight of tetramers, C) a fraction comprising 20 to 35% by weight of trimers, 40 to 60% by weight of tetramers and 13 to 27% by weight of pentamers, d) a fraction comprising 35 to 55% by weight of trimers and 40 to 60% by weight of tetramers, e) a fraction comprising 45 to 65% by weight of tetramers, 22 to 34% by weight of pentamers and 5 to 15% by weight of C56To C64A fraction of hexamers, f) a fraction comprising from 12 to 24% by weight of trimers, from 37 to 57% by weight of tetramers, from 13 to 25% by weight of pentamers and from 6 to 18% by weight of hexamers +, g) a fraction comprising from 30 to 42% by weight of tetramers, from 27 to 18% by weight of hexamers +A fraction of 39 wt.% pentamer, 10 wt.% to 22 wt.% hexamer, and 9 wt.% to 21 wt.% heptamer +, and h) any combination of fractions a) to g).
Fig. 2 shows that one or more fractions can exit fractionation zone 50 via streams 52a, 52b, … … 52n, where "n" represents the number of streams formed through fractionation zone 50. The present invention contemplates that a single fraction or more than one fraction (e.g., streams 52a, 52b, … … 52n) can be formed in fractionation zone 50. In one embodiment, the number "n" of streams 52a-n formed by fractionation zone 50 can be 2,3, 4,5, 6,7, 8, 9, 10, or more.
After fractionating the oligomer product (or heavier oligomer portion thereof) into one or more fractions, the unsaturation of at least one of the one or more fractions may be reduced by fractionating at least one of the one or more fractions (e.g., from a fraction comprising all or a portion of the oligomer product, comprising all or a portion ≧ C19Oligomer, containing all or part ≧ C26Oligomers, at least one fraction formed from a stream comprising all or a portion of the trimer + oligomers) is hydrogenated to form polyalphaolefins. Fig. 2 shows that at least one of the one or more fractions in streams 52a-n (represented by the dashed line) can be passed to hydrogenation zone 60 for hydrogenation. The present invention contemplates that at least one (one or any combination) of streams 52a-n can be fed (separately, simultaneously, separately and simultaneously, periodically, continuously or any combination thereof) to hydrogenation zone 60. For example, the disclosed embodiments contemplate that streams 52a and 52b may be fed to hydrogenation zone 60, and stream 52n may not be fed to hydrogenation zone 60; alternatively, stream 52a may be fed to hydrogenation zone 60, and streams 52b and 52n may not be fed to hydrogenation zone 60; and so on. It is further contemplated that the hydrogenation zone 60 can include one or more hydrogenation units (e.g., one hydrogenation unit per stream to be hydrogenated). It is further envisaged that each stream to be hydrogenated may be hydrogenated separately in a single hydrogenation unit.
In the hydrogenation unit in the hydrogenation zone 60, the hydrogenation of one or more fractions can be achieved with the aid of the present invention by any means known to the person skilled in the art. The hydrogenation unit in hydrogenation zone 60 can hydrogenate the unsaturated double bonds of one or more fractions to produce a hydrogenation product comprising, for example, polyalphaolefins. In some embodiments, one or more of the fractions may be stored for a period of time prior to hydrogenation in the hydrogenation unit within hydrogenation zone 60.
In one embodiment, any of the one or more fractions of all or a portion of the oligomer product separated by the various embodiments described herein can be hydrogenated by reaction with hydrogen to form a polyalphaolefin. Generally, the hydrogenation can comprise contacting one or more fractions of all or a portion of the oligomer product with a hydrogenation catalyst under conditions that can hydrogenate one or more fractions of all or a portion of the oligomer product to form polyalphaolefins. In some embodiments, one or more fractions of all or a portion of the oligomer product may be hydrogenated to produce a polyalphaolefin having any bromine number or bromine index as described herein.
In one embodiment, the hydrogenation catalyst may comprise, or consist essentially of, supported group 7, group 8, group 9, and group 10 metals. In some embodiments, the hydrogenation catalyst may be selected from the group consisting of one or more of the following: ni, Pd, Pt, Co, Rh, Fe, Ru, Os, Cr, Mo, and W supported on silica, alumina, clay, titania, zirconia, or mixed metal oxide supports. In other embodiments, the hydrogenation catalyst may be nickel supported on diatomaceous earth, platinum or palladium supported on alumina, or cobalt-molybdenum supported on alumina; alternatively, it may be nickel supported on diatomaceous earth; alternatively, it may be platinum or palladium supported on alumina; or alternatively, may be cobalt-molybdenum supported on alumina. In still other embodiments, the hydrogenation catalyst may be one or more of the group consisting of: nickel supported on diatomaceous earth, silica, alumina, clay or silica-alumina.
Generally, the hydrogenation of one or more fractions of all or a portion of the oligomer product to form polyalphaolefins can be carried out in any type of process and/or reactor that can hydrogenate one or more fractions of all or a portion of the oligomer product to a desired bromine number or bromine index. In one embodiment, hydrogenating the one or more fractions to form polyalphaolefins may be performed in a batch process, a continuous process, or any combination thereof, optionally may be performed in a batch process; or alternatively may be carried out in a continuous process. In some embodiments, hydrogenating all or a portion of one or more fractions of the oligomer product to form polyalphaolefins can be performed in a slurry reactor, a continuous stirred tank reactor, a fixed bed reactor, or any combination thereof; alternatively, it may be carried out in a slurry reactor; alternatively, it may be carried out in a continuous stirred tank reactor; or alternatively, it can be carried out in a fixed bed reactor.
Typically, the product polyalphaolefin (i.e., a hydrogenated fraction of all or a portion of the oligomer product) is removed from the hydrogenation unit as streams 62 a-n. The product polyalphaolefin can be filtered to separate the hydrogenation catalyst and/or catalyst fines from the polyalphaolefin. In addition, the polyalphaolefin can be distilled to further purify the polyalphaolefin; optionally, distilled to form two or more compositions comprising, or consisting essentially of, polyalphaolefins having different nominal viscosities; or alternatively, distilled to further purify the polyalphaolefin and form two or more compositions comprising, or consisting essentially of, polyalphaolefins having different nominal viscosities.
The amount of hydrogenation catalyst used to hydrogenate one or more of the fractions depends on the hydrogenation catalyst employed and the characteristics of the particular hydrogenation process. In general, the amount of hydrogenation catalyst used can be any amount that produces the desired bromine number (or bromine index) of the polyalphaolefin under the desired conditions capable of forming the polyalphaolefin. In non-fixed bed hydrogenation processes (such as slurry reactors or continuous stirred tank reactors, among others), the amount of hydrogenation catalyst used for the hydrogenation may range from 0.001 wt% to 20 wt%, from 0.01 wt% to 15 wt%, from 0.1 wt% to 10 wt%, or from 1 wt% to 5 wt%. In a fixed bed process, the WHSV (weight hourly space velocity) of the one or more fractions for the hydrogenation catalyst may range from 0.01 to 10, from 0.05 to 7.5, or from 0.1 to 5. The weight% of the hydrogenation catalyst is based on the total weight of the hydrogenation catalyst and the one or more fractions being hydrogenated.
Generally, the conditions capable of hydrogenating all or a portion of one or more fractions of the oligomer product may comprise hydrogen pressure, temperature, contact time, or any combination thereof; alternatively, hydrogen pressure and temperature may be included; alternatively, hydrogen pressure, temperature, and contact time may be included. In one embodiment, the hydrogenation temperature range that may be used as conditions capable of hydrogenating all or a portion of one or more fractions of the oligomer product may be 25 ℃ to 350 ℃,50 ℃ to 300 ℃,60 ℃ to 250 ℃, or 70 ℃ to 200 ℃. In one embodiment, the hydrogen pressure range that may be used as conditions capable of hydrogenating all or a portion of one or more fractions of the oligomer product may be 100kPa to 10MPa, 250kPa to 7MPa, 500kPa to 5MPa, or 750kPa to 2 MPa. In one embodiment, the contact time that may be used as conditions capable of hydrogenating all or a portion of one or more fractions of the oligomer product may range from 1 minute to 100 hours, 2 minutes to 50 hours, 5 minutes to 25 hours, or 10 minutes to 10 hours. Additional information regarding hydrogenation to produce polyalphaolefins (e.g., olefin oligomers such as one or more fractions that may be produced by embodiments described herein) to form a plurality of polyalphaolefins may be found in U.S. Pat. No. 5,573,657 and "Lubricant Base Oil Hydrogen Refining Processes" (Lubricant Base Oil and Wax Processing), pages 119 to 152, aviino sequeria, jr., Marcel Dekker, inc., NY (1994)).
It is contemplated by the present invention that separator 40 and fractionation zone 50 of fig. 2 can be combined into a single unit in which all or a portion of the components (e.g., unreacted monomer, oligomer product, organic reaction medium, if used) in second stream 24 can be fractionated and separated so that unreacted monomer, any organic reaction medium (if used), or any combination thereof can be recovered in a first set of one or more fractions and the oligomer product can be recovered in a second set of one or more fractions of the oligomer product; or alternatively, unreacted monomer, any organic reaction medium (if used), lighter oligomers (e.g., dimer, ≦ C18Oligomer or. ltoreq.C25Oligomer), or any of themThe desired combination may be recovered in a first set of one or more fractions and the heavier oligomers may be recovered in a second set of one or more fractions. That is, in some embodiments, the oligomer product or the heavier portion of the oligomer product can be separated to contain all or a portion of the oligomer product or heavier oligomers (e.g.,. gtoreq.C) while separating from the unreacted monomers and organic reaction medium (if used)19Oligomer, ≧ C26Oligomers or trimers + oligomers), or consist of, or consist essentially of one or more fractions thereof. In such an embodiment, unreacted monomer and organic reaction medium (if used) exiting the single unit may optionally be recycled and optionally contacted with molecular sieves, alumina, silica gel, activated carbon, or any combination thereof in a contacting unit (not shown) as described with respect to fig. 2 before being recycled to reaction zone 10.
Fig. 3 shows another embodiment for separating one or more fractions of the hydrogenated oligomer product and hydrogenating at least one of all or a portion of the one or more fractions of the oligomer product. In the embodiment of fig. 3, the second stream 24 (which may optionally be treated to remove residual catalyst system components) is received by a separator 40, and the separator produces a third stream 42 and a fourth stream 44 having the embodiment discussed with respect to fig. 2. Further, as in fig. 2, the components of the third stream 42 can optionally be contacted with molecular sieves, alumina, silica gel, activated carbon, or any combination thereof in a contacting unit before optionally being recycled to the reaction zone 10 of fig. 1. It should be noted that although fig. 3 shows that the third stream 42 is totally recycled to the reactor, it is contemplated that only a portion of the third stream 42 may be recycled to the reaction, may be further separated to provide a stream comprising unreacted monomer, lighter oligomers (if present in the third stream 42), and/or all or a portion of the components may be stored for a period of time before being recycled to the reaction zone 10 of fig. 1.
Unlike the example of FIG. 2, the fourth stream 44 of FIG. 3 flows to a hydrogenation unit 70 where the oligomer product or the heavier portion of the oligomer product (e.g.,. gtoreq.C)19Oligomer, ≧ C26Oligomers or trimers + oligomers) are hydrogenated to produce hydrogenated oligomer products or hydrogenated heavier fractions of oligomer products. In some embodiments, the oligomer product or the heavier portion of the oligomer product (e.g.,. gtoreq.C)19Oligomer, ≧ C26Oligomer or trimer + oligomer) may be stored for a period of time before entering hydrogenation unit 70. The hydrogenated oligomer product may comprise, consist essentially of, or consist of all or a portion of the oligomer product. The hydrogenated heavier portion of the oligomer product may comprise, consist essentially of, or consist of all or part of the heavier oligomer product. The hydrogenation conditions of hydrogenation unit 70 may be similar to those disclosed for the hydrogenation unit of hydrogenation zone 60 in fig. 2. Hydrogenated oligomer product or hydrogenated heavier fraction of oligomer product (e.g.. gtoreq. hydrogenated C)19Oligomer, hydrogenated ≥ C26Oligomer or hydrogenated trimer + oligomer) flows from hydrogenation unit 70 to fractionation zone 80 in stream 72. In some embodiments, the hydrogenated oligomer product or the hydrogenated heavier fraction of the oligomer product (e.g., ≧ hydrogenated C19Oligomer, hydrogenated ≥ C26Oligomer or hydrogenated trimer + oligomer) may be stored for a period of time prior to entering the fractionation zone 80. Fractionation zone 80 can function under similar conditions as disclosed for fractionation zone 50 in fig. 2, except that fractionation zone 80 and the conditions therein are configured to facilitate fractionation of the hydrogenated oligomer product or the hydrogenated heavier portion of the oligomer product into one or more hydrogenated fractions. In various embodiments, the hydrogenated oligomer product is fractionated into one or more hydrogenated fractions comprising all or a portion of the hydrogenated oligomer product; hydrogenated ≥ C19The oligomers are fractionated to contain hydrogenated ≧ C19One or more hydrogenated fractions of all or part of the oligomers; hydrogenated ≥ C26The oligomers are fractionated to contain hydrogenated ≧ C26One or more hydrogenated fractions of all or part of the oligomers; or the hydrogenated trimer + oligomers are fractionated into all or part of the fraction comprising hydrogenated trimer + oligomersOne or more hydrogenated fractions are separated. In general, the fractionation zone 80 in FIG. 3 can form a hydrogenated form of any of one or more fractions comprising all or a portion of the oligomer product, comprising all or a portion ≧ C19Hydrogenated form of any of one or more fractions of oligomers, comprising all or part ≧ C26Hydrogenated versions of one or more fractions of oligomers, or hydrogenated versions of one or more fractions containing all or a portion of the trimer + oligomers that can be formed from the fourth stream 44 of fig. 2. The hydrogenated form of any of these one or more fractions is described in more detail herein and can be used to further describe the processes described herein.
Fig. 3 shows that one or more hydrogenated fractions can exit fractionation zone 80 via streams 82a, 82b, … … 82n, where "n" represents the number of hydrogenated streams formed in fractionation zone 80. The present invention contemplates that a single hydrogenated fraction or more than one hydrogenated fraction may be formed in fractionation zone 80 (e.g., streams 82a, 82b, … … 82 n). In one embodiment, the number "n" of streams 82a-n formed by the fractionation zones can be 2,3, 4,5, 6,7, 8, 9, 10, or more.
Embodiments of the present invention contemplate that after fractionating the hydrogenated oligomer product (or the hydrogenated heavier portion of the oligomer product) into one or more hydrogenated fractions in fractionation zone 80, any of the one or more hydrogenated fractions in streams 82a-n may be subjected to a finishing hydrogenation by hydrogenating any of the one or more hydrogenated fractions. In embodiments having a finishing hydrogenation step, any of streams 82a-n may be fed to the finishing hydrogenation unit in the same manner as described for streams 52a-n fed to the hydrogenation unit of hydrogenation zone 60 in fig. 2. In some embodiments, one or more hydrogenated fractions may be stored for a period of time prior to finishing hydrogenation.
Figure 4 shows another alternative embodiment for separating one or more fractions of the hydrogenated oligomer product. In the embodiment of fig. 4, a second stream 24 (which may optionally be treated to remove residual catalyst system components) is received by hydrogenation unit 100. It can be seen that there is no separation unit 40 as shown in fig. 2 and 3 and that no components are recycled to the reaction zone 10 prior to hydrogenation in the embodiment of fig. 4. Conversely, all components (e.g., unreacted monomer, organic reaction medium, oligomer products, or combinations thereof) flow in second stream 24 to hydrogenation unit 100. The unreacted monomer, organic reaction medium (if used), and oligomer product in second stream 24 are hydrogenated in hydrogenation unit 100 to produce hydrogenated stream 102 comprising, consisting essentially of, or consisting of the hydrogenated oligomer product, organic reaction medium (if used), and hydrogenated unreacted monomer. The hydrogenated oligomer product may comprise all or part of the oligomer product. The hydrogenation conditions of hydrogenation unit 100 can be similar to those described for the hydrogenation unit in hydrogenation zone 60 in fig. 2.
The hydrogenated stream 102 can flow from the hydrogenation unit 100 to the fractionation zone 110. In the fractionation zone 110, the hydrogenated oligomer product is separated from the hydrogenated stream 102 into one or more hydrogenated fractions comprising all or a portion of the hydrogenated oligomer product, thereby obtaining polyalphaolefins. In some embodiments, the hydrogenated stream 102 may be stored for a period of time before entering the fractionation zone 110. The fractionation zone can further provide 1) a stream comprising hydrogenated unreacted monomer, a stream comprising an organic reaction medium, or 3) a combination of 1) and 2). In some embodiments, the organic reaction medium can be recycled to reaction zone 10 of fig. 1. In some embodiments, the organic reaction medium can be stored for a period of time before being recycled to reaction zone 10 of fig. 1.

Examples 1 to 5 show that oligomerization of 1-decene with N- (N-butyl) pyridinium chloroaluminate in the absence of a halide component at temperatures ranging from 20 ℃ to 95 ℃ produces a very heavy oligomer distribution that is heavier than the oligomer distribution produced at similar temperatures using a halide component and an ionic liquid. For example, the average Mn of the oligomeric product produced in the absence of the halide component at 20 ℃ was >897g/mole (example 1), while the oligomeric product produced using the halide component had an average Mn of >628 g/mole (example 4). Examples 1-5 show that the use of a halide component can be used to reduce the average molecular weight of the oligomer product produced using an ionic liquid catalyst system.

The SimDist data of examples 6-9 indicate that the absence of the halide component (example 6) produces a significantly heavier oligomer distribution than when the oligomerization reaction is carried out using a catalyst system comprising an ionic liquid and a halide component. This observation is further confirmed by fig. 5, which depicts overlapping gas chromatograms of comparative example 6 and example 8 products comprising unreacted monomer and oligomer products. As can be seen, the gas chromatography of comparative example 6 shows that the corresponding product contains a small amount of trimer to pentamer oligomers and the majority of the oligomers are heavy C60+An oligomer. In contrast, the gas chromatography of example 8 showed that the corresponding product contained clear C10Multiple of oligomer (e.g. C)20、C30、C40、C50、C60Etc.) mainly containing a dimer (C)20) Trimer (C)30) Tetramer (C)40) Pentamer (C)50) And hexamer (C)60) An oligomer. Thus, fig. 5 shows that the use of a catalyst system comprising an ionic liquid and a halide component such as, for example, t-butyl chloride, is more selective for lower carbon number (or lighter) oligomer product distribution. The data further show that, although the distribution generated in example 2 of U.S. patent No. 7,572,944 is not as heavy as the distribution generated in example 6, the distribution generated in example 2 of U.S. patent No. 7,572,944 is still significantly heavier than the distributions generated in examples 8 and 9And are even more important.
To further qualitatively assess the differences between examples 6,7, 8 and 9, the data from the SimDist analysis of examples 6,8 and 9 was used to determine the amount of monomers and various oligomers present in examples 6,8 and 9. This data is then used to determine the approximate true boiling point, where C10、C20、C30、C40、C50、C60And C70+The fractions will fall into the SimDist data. These ranges were used to determine the C present in the oligomerization reaction of example 7 (i.e., example 2 of U.S. patent No. 7,572,944) from its corresponding SimDist data10、C20、C30、C40、C50、C60And C70+Approximate amount of distillate fraction.

Review of the oligomer distribution data for the oligomer products of examples 6-9 confirmed the above observations obtained using the SimDist data given in tables 6-3. Specifically, 1) the oligomer product of example 6 produced in the absence of a halide component has a very heavy oligomer distribution in which about 88 wt.% of the oligomer product has 60 or more carbon atoms and about 12 wt.% of the oligomer product has 20 to 50 carbon atoms, 2) the oligomer product of example 7 (i.e., example 2 of U.S. patent No. 7,572,944) has a heavy oligomer distribution in which 70 wt.% of the oligomer product has 60 or more carbon atoms and about 30 wt.% of the oligomer product has 20 to 50 carbon atoms, and 3) examples 8 and 9 have a significantly lower oligomer distribution in which the oligomer product has less than 35 wt.% (about 34 wt.% and 29 wt.%, respectively) of oligomers having 60 or more carbon atoms and a majority of the oligomer product has greater than 65 wt.% (about 66 wt.% and 71 wt.%, respectively), Oligomers having 20 to 50 carbon atoms. The results of comparative example 6 are comparable to comparative example 1 above (which yields 82.7 wt% C)60+Oligomers, see tables 1-3) to confirm low levels of 1-decene and N- (N-butyl) pyridine chloroaluminate at 20 ℃ in the absence of halide componentsThe polymerization reaction produces a heavier oligomer product. The data shows that a catalyst system comprising an ionic liquid and a halide component can be used to produce an oligomer product having an oligomer distribution such that: the oligomer distribution has a significant amount of commercially attractive oligomers having 20 to 50 carbon atoms.
With respect to comparative example 7 and examples 8 and 9, without being bound by theory, it appears that using a large amount of ionic liquid (or described as a low molar ratio of double bonds in the monomer to Al in the ionic liquid) results in an oligomer product having a significant amount of oligomers with greater than 60 carbon atoms. Surprisingly, reducing the amount of ionic liquid (alternatively described as a high molar ratio of double bonds in the monomer to Al in the ionic liquid) increases the amount of oligomers having from 20 to 50 carbon atoms in the oligomer product.
Without being bound by theory, the halide component (e.g., t-butyl chloride) appears to control the termination of the oligomerization product. The presence of the halide component appears to cause the carbon number distribution, boiling point distribution, and molecular weight distribution of the oligomer product to shift downward. Without being bound by theory, it appears that higher reaction temperatures may also affect the growth of oligomeric chains — perhaps by increasing the reaction rate and concentration of chain growth oligomers (e.g., forming more lower molecular weight chains and forming fewer higher molecular weight chains).
Examples 10 to 21
In examples 10 to 21, oligomerization of 1-decene was carried out in the presence of N- (N-butyl) pyridinium chloroaluminate ionic liquid and tert-butyl chloride as the halide component. Diluent n-nonane was also used in examples 18 to 21.
A250 mL two-necked round bottom flask equipped with a magnetic stir bar and a PTFE septum was prepared in a nitrogen glove box. To a round bottom flask was added the desired amounts of 1-decene and n-nonane (if used). The desired amount of tert-butyl chloride was then added to the round bottom flask. The contents of the round bottom flask were then heated to the desired initial temperature ranging from 63 ℃ to 135 ℃. Once the contents of the round bottom flask were in thermal equilibrium, the N- (N-butyl) pyridinium chloroaluminate ionic liquid was added slowly via syringe over the first few minutes to produce a reaction mixture. The rapid exotherm was typically observed via measurements made by a thermocouple placed inside the flask through a PTFE septum. The reaction mixture initially had a relatively uniform orange color during the exotherm and remained orange for the remainder of the reaction. The oligomerization reaction was allowed to proceed for a period of 15 minutes or 60 minutes. Sampling tests showed that the reaction was generally complete in less than 15 minutes.
At the desired reaction time, an aliquot of the reaction mixture (equivalent to the reaction zone effluent) was removed from the round bottom flask. The aliquot was treated with 1-butanol to deactivate the ionic liquid catalyst system, resulting in a treated colorless reaction mixture, and the deactivated ionic liquid catalyst system residue was precipitated. An aliquot of the 1-butanol treated reaction mixture was then taken through a syringe and passed through a PTFE filter to give a solution of unreacted monomer and oligomer product. The unreacted monomer and oligomer products were then analyzed by gas chromatography using a 5m SimDist column from Agilent technologies. The monomer conversion and molecular weight distribution Mn of the unreacted monomer and oligomer products were calculated analytically by comparing the oligomer fraction with the pure starting material using n-pentadecane as an internal standard. A summary of the reaction conditions for each of examples 10 to 21 is shown in Table 10-1 and Table 10-2.

The data shown in tables 10-1 to 10-6 indicate that the composition of the catalyst system and oligomerization conditions can be used to adjust the oligomer distribution of the oligomer product. For example, the composition and oligomerization conditions of the catalyst systems in examples 13 and 18 to 21 produced lighter oligomer products than the oligomerization conditions in examples 10 to 12 and 14 to 17.
Examples 22 to 38
In examples 22 to 38, 1-decene was oligomerized in the presence of N- (N-butyl) pyridinium chloroaluminate ionic liquid, t-butyl chloride as the halide component, and the diluent N-nonane. A250 mL two-necked round bottom flask equipped with a magnetic stir bar and a PTFE septum was prepared in a nitrogen glove box. A1: 1 volume ratio 1-decene/diluent mixture was added to the round bottom flask. The diluent mixture contained 80mL of n-nonane and 20mL of n-pentadecane. The desired amount of tert-butyl chloride was then added to the round bottom flask. The contents of the round bottom flask were then heated to the desired temperature ranging from 40 ℃ to 100 ℃. Once the contents of the round bottom flask were in thermal equilibrium, the desired amount of N- (N-butyl) pyridinium chloroaluminate ionic liquid was added slowly via syringe over the first few minutes to produce a reaction mixture.

The data presented in tables 22-1 to 22-9 indicate a trimer + (C) of about 5.2cSt30+) The viscosity can be obtained at a reaction temperature of about 100 ℃. High maximum reaction temperature values result in high levels of dimer, which can affect product properties (more volatile, undesirable flash/ignition point), and which can allow recycle streams of dimer in a continuous process.
The data shown in tables 22-1 to 22-9 indicate that a wide range of oligomer distributions having different shapes and widths can be formed by adjusting one or more of the molar ratio of double bonds in the monomer to Al in the ionic liquid, the molar ratio of Cl in the halide component to Al in the ionic liquid, the oligomerization temperature, and the oligomerization time. The data shown in tables 22-1 to 22-9 show that generally increasing the concentration of ionic liquid increases the conversion and increases the viscosity of the product, while increasing the concentration of halide component (e.g., t-butyl chloride) significantly increases the conversion, but decreases the viscosity of the product as compared to increasing the ionic liquid concentration. It can also be seen that the oligomer product distribution can be adjusted to favor trimer production.
Examples 39 and 40
In example 39, the product mixture of example 9 was hydrogenated using a nickel-based hydrogenation catalyst. The hydrogenated product mixture was completely colorless and had a bromine index<200. The hydrogenated product mixture is then fractionated by vacuum distillation into 1) C10And C20(650 ℃ F.) fraction and 2) fraction containing residual hydrogenated oligomers (e.g., trimer + (C)30+) Oligomeric polyalphaolefin product). The polyalphaolefin product fraction has a viscosity of 8.0 cSt. The chloride content of the polyalphaolefin product was measured by X-ray fluorescence Spectroscopy (XRF) as<0.3ppmw。
In example 40, the oligomer product of example 5 was hydrogenated using a nickel-based hydrogenation catalyst and then fractionated by vacuum distillation to 1) C, similar to the oligomer product of example 910And C20(650 ℃ F.) fraction and 2) fraction containing residual hydrogenated oligomers (e.g., trimer + (C)30+) Oligomeric polyalphaolefin product). The polyalphaolefin product fraction had a viscosity of 9.6 cSt.
Figures 6 and 7 show chromatograms of gas chromatographic analysis of the hydrogenated oligomer product and the polyalphaolefin product of examples 39 and 40, respectively. In fig. 6, the chromatogram of the gas chromatographic analysis of the hydrogenated product mixture prior to distillation in example 39 is above the chromatogram of the gas chromatographic analysis of the polyalphaolefin product of example 39 produced by distilling the hydrogenated product mixture. In fig. 7, the chromatogram of the gas chromatographic analysis of the hydrogenated product mixture prior to distillation in example 40 is above the chromatogram of the gas chromatographic analysis of the polyalphaolefin product fraction of example 40 produced in the distillation of the hydrogenated product mixture.
